BARREL-VENTING BUNG.

Application filed May 10, 1926.

The invention relates to improvements in bungs for admitting air to barrels when contents must be withdrawn therefrom, but for ordinarily excluding air, which is essential when storing certain kinds of liquids.

It is the object of the invention to provide a new and improved venting bung which is extremely simple and inexpensive and possesses no parts which can be injured by rolling of a barrel equipped with the invention.

lVith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Fig. 1 is a transverse section of a barrel, partly in elevation, showing the applicatlon of the invention.

Fig. 2 is an elevation of a portion of the barrel and the invention applied thereto.

Fig. 3 is an enlarged vertical section on line of Fig. 2 showing the airadm1tting valve in its normally closed position.

Fig. 4 is a view similar to Fig. 3 but illustrating the manner in which the valve is opened by hand.

In the drawing above briefly described, the numeral 5 designates a one-piece bung preferably formed from wood and having a tapered inner end portion 6 for reception in the usual bung-receiving opening 7. The inner extremity 8 of the bung 5 is flat and disposed at right angles to the axis of said bang, and along said axis, the bung 1s formed with a bore 9 which opens through said inner surface 8. Opening through the outer end of the bung and communicating with the bore 9 is a counterbore 10, and leading from this counterbore through the sur face 8, is a venting port 11.

A straight metal stem 12 passes slldably through the bore 9 and at its inner end 1s provided with a valve preferably consisting of a metal washer 13 and a d1sk 14 adapted to seat against the surface 8, said disk being preferably formed of rubber. The washer 13 is preferably threaded on the stem 12 and is held thereon by a lock nut 15.

Serial No. 108,099.

The outer end portion of the stem 12 is received in the counter-bore 10 and is formed with a head 16 which does not project beyond said counterbore.

Surrounding the stem between this head and the inner end of the counterbore 10 is a coiled compression spring 17 which serve to normally move the stem outwardly, thus tightly seating the valve disk 14 against the flat inner end of the bung 5, said disk then closing the port 11 to exclude air from the barrel.

The counterbore 10 is of such size that the user of the device may insert one of his fingers into said counter-bore to engage the head 16, thereby depressing the stem 12 and opening the valve as shown in Fig. 4. Thus, air is admitted through the venting port 11 so that discharge of liquid can take place.

It will be seen from the foregoing that the invention is of extreme simplicity, may be therefore inexpensively manufactured and marketed, and will not get out of order. Moreover, there are no projecting parts to interfere with rolling of the barrel or to possibly be injured by such rolling.

I claim A device of the class described comprising a one-piece barrel bung having a central bore which opens through its inner end, a central counterbore opening through its outer end, and an off-center port from said counterbore through said inner end, stem slidable in said bore and having a valve at its inner end to seat against the inner end fixed my signature.
